BATON ROUGE, La. — Another strong performance from freshman right-hander AJ Labas on the mound and a four-run fifth inning propelled the LSU baseball team to a 7-5 victory and a series win over the No. 4 Arkansas Razorbacks Sunday afternoon at Alex Box Stadium, Skip Bertman Field.

With the win, LSU improved to 28-20 overall and 12-12 in the SEC, while Arkansas fell to 33-15 on the year and 14-10 in conference play.

The Tigers will return to action Wednesday for a non-conference midweek matchup with McNeese State at 6:30 p.m. CT at The Box.

Labas (6-1) picked up the win Sunday, pitching six innings and giving up just one earned run while striking out three with no walks.

Arkansas starter Isaiah Campbell (3-5) took the loss after giving up five earned runs in 4.1 innings of work.

LSU right-hander Matthew Beck was brilliant in relief, firing three shutout innings with no hits, one walk and three strikeouts to earn his first save of the season.

Sunday’s win secured LSU’s seventh straight series victory over Arkansas and the Tigers’ 13th series win over the Razorbacks in the last 14 seasons.

“We knew how important this series was for us, and even though we lost Game 1 on Friday, I thought we played loose and confident the entire weekend,” said LSU coach Paul Mainieri. “We decided to throw caution to the wind, let it rip and have fun, and we earned two wins against a great Arkansas team.

“AJ Labas went out there and gave us six unbelievable innings, and Matthew Beck was phenomenal over the last three innings. It was a tremendous victory, and it gives our players an amazing feeling of belief in themselves.”
